i am your brother, i am your neighbor. this is the "cbs evening news" with scott pelley. >> pelley: this is our western edition. the latest tweet from the president-elect could signal a reversal of nearly five decades of u.s. nuclear policy. since 1963, presidents, both republican and democrat, have agreed with russia to limit nuclear weapon development. most recently, in 2010, president obama signed a deal to cut the number of missile launchers in half and limit deployed warheads on both sides. but today, donald trump suggested that policy may not be his policy. here's julianna goldman. >> reporter: in just 140 characters, president-elect donald trump signaled a major shift in u.s. foreign policy, tweeting: transition officials

transition officials didn't say what prompted the tweet, but it came the same day that russian president, vladimir putin, said moscow needs to strengthen the military potential of strategic nuclear forces. >> i think the tweet was ambiguous, and it was hard to figure out what exactly he meant. u. reporter: former u.s. ambassador to nato, nicholas burns. r in nuclear diplomacy and in diplomacy in general, you want to be clear, most of the time-- especially with your adversaries -- about what you're willing to do and not willing to do. >> reporter: a trump aide later tried to clarify saying the president-elect was, "referring to the threat of nuclear proliferation and the critical need to prevent it." during the campaign, mr. trump also sent conflicting messages on nuclear policy. ho look, nuclear should be off the table. ert would there be a time when it could be used? possibly. >> okay, the trouble is when you said that-- t reporter: today's confusion overshadowed mr. trump's long- lonted white house staff announcements, including naming

former campaign manager unllyanne conway as counselor to ige president, making her the top-ranking woman in the west wing. former republican national committee spokesperson sean spicer will be the next white house press secretary. and longtime aide hope hicks will serve as the director of strategic communications. a day after mr. trump said he still favors a muslim registry, president obama made that more difficult. scott, while it hadn't been used in five years, he ended a 9/11ram enacted after 9/11 that registered visitors from countries with active terrorist groups. >> pelley: julianna goldman covering the transition. julianna, thank you. today, the president-elect's daughter, ivanka, was berated by two strangers on a flight that nes scheduled to depart new york. this picture turned up on social media. one of the men reportedly told miss trump that her father was "ruining the country." the men were kicked off the plane before it departed. the trump transition team has been sending questionnaires to

cabinet departments, not at all tusual, but some of the questions sent to the state rgpartment are raising concerns. and margaret brennan is following this. >> reporter: the memo shared dith cbs news requested details on existing programs and activities to promote gender equality, such as ending gender- based violence. as well as a list of jobs that handle those issues. it did not state why the idformation was needed but raised concern that the trump ceministration might want to cancel state department initiatives championed by former secretary hillary clinton. spokesman john kirby: >> i can't discount the notion that in all aspects of a change in leadership here that there's going to be anxiety. b reporter: the memo did not ask for the names of officials ico work on these programs, unlike a controversial questionnaire sent by the trump ntam to the energy department earlier this month. it requested a list of programs and staffers "essential to deeting the goals of president

obama's climate action plan." the questionnaire prompted house foreign affairs committee democrats to urge secretary kerry in a letter last week not to single out his employees. today, kirby said there is a limit to the help the state department will provide. >> obviously, we would have concerns if-- if, for instance, there were issue-specific lists of names that were being epovided. >> reporter: and kirby also said that the request for organizations and names and details were normal. scott. el pelley: margaret brennan at the state department, thank you, margaret. there's no question that hillary clinton won the popular vote. it is official now. all 50 states and d.c. have certified their totals. nearly 66 million americans voted for clinton, jut under 63

as after a dvt blood clot,ital i sure had a lot to think about. what about the people i care about? ...including this little girl. and what if this happened again? i was given warfarin in the hospital, but wondered, was this the best treatment for me? so i asked my doctor. and he recommended eliquis. eliquis treats dvt and pe blood clots and reduces the risk of them happening again. yes, eliquis treats dvt and pe blood clots. eliquis also had significantly less major bleeding

than the standard treatment. both made me turn around my thinking. don't stop eliquis unless your doctor tells you to. eliquis can cause serious and in rare cases fatal bleeding. don't take eliquis if you have an artificial heart valve or abnormal bleeding. if you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. while taking eliquis, you may bruise more easily ...and it may take longer than usual for bleeding to stop. seek immediate medical care for sudden signs of bleeding, like unusual bruising. eliquis may increase your bleeding risk if you take certain medicines. tell your doctor about all planned medical or dental procedures. eliquis treats dvt and pe blood clots. plus had less major bleeding. both made eliquis the right treatment for me. ask your doctor if switching to eliquis is right for you. when i was too busy with the kids to get a repair estimate. liberty did what? yeah, with liberty mutual all i needed to do to get an estimate was snap a photo of the damage and voila! voila!
